--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- So the issue is not the rev. in question (well, it triggers it). PRE should still work since there is the unconditional dereference in the loop. And it does when we allow ANTIC_IN to grow again during iteration (r8-7285-gec64ffc8501c20 installed something to limit this). Of course it's testcase now still works, even w/o its fix. I'll see to understand if the issue in the old PR is now fixed by other means (gcc.dg/torture/pr84830.c).
